The heat exchanger is a heat exchange device between two immiscible media. It consists of an outer cylinder with sealing plates at both ends-two support plates and many heat exchange tubes. The tube heat exchanger has a simple and compact structure, high heat transfer coefficient and good condensation effect when the structure design and operating conditions are reasonable, and it is suitable for the condensation and recovery of various solvent vapors.

Gas heat exchange requires a long heat exchange path, so this type of heat exchanger is designed as a long strip.
